A semitruck fatally struck a sheriff’s deputy in Indiana while he was assisting a stranded motorist along an interstate, according to local officials.

“This is a heartbreaking loss for our law enforcement family and for the entire Delaware County community,” Jeff Stanley, the chief deputy for the Delaware County Sheriff’s Office, said in a statement on Wednesday.

The tragedy occurred in the early hours of Wednesday morning, after officials received calls at approximately 3:30 a.m. of a disabled vehicle along Interstate 69, officials said.

The Delaware County sheriff’s deputy, who was identified as Corporal Blake Reynolds, responded to the scene and found a semitruck partially in the roadway, officials said.

The deputy stopped behind the disabled vehicle to “provide protection for the driver” and activated his emergency lights, Indiana State Police Sgt. Scott Keegan said during a press conference on Wednesday.

While Reynolds was outside his vehicle, another semitruck traveling northbound “lost control and collided with the deputy’s vehicle and the disabled semi that was on the side of the road,” Keegan said, calling the crash a “tragic event.”

“Despite immediate emergency response efforts, the deputy did not survive his injuries,” Stanley said.

The driver who struck Reynolds was transported to a local hospital and was undergoing surgery, but Keegan said his medical condition is not known at this time.

The sheriff’s officials said no further details on the crash will be provided at this time “out of respect for the ongoing investigation and the family’s privacy.”

Reynolds joined the Delaware County Sheriff’s Office in 2022 and “quickly distinguished himself through his hard work, professionalism and leadership,” the sheriff’s office said in a statement.

“His passing is an immeasurable loss to his family, his brothers and sisters in uniform and the entire community he served with pride,” Stanley said.
